Hi I am doing telecommunication engineering and my final year project is "Design and analysis of UWB micro strip patch antenna, and I have to work on it now I am little bit confuse how to get started.
I have to design it using software HFSS. Please help me to learn this software and parameters......

Try to get inside HFSS and replicate the examples that are illustrated in the user's manual.. there are many practical electromagnetic structures demonstrated in the manual. You can replicate those and have an idea about HFSS
